>>29923547I have a Wii U. You're not missing much. The few games of value are generally either backwards compatible Wii games, weird and niche (ex: Bayonetta, Wii Fit U, Pokken Tournament, ect) or Mario related. Some of the E-shop titles are nice (the latest Fatal Frame, Shantae, Earthbound, ect) and at least give a legal way to play what otherwise would have to be pirated or emulated.
Don't get me wrong: I like those things and many wii games are pretty cheap right now making it easy to get a good collection going. If you're not into them, though, you may want to wait a year or so for the release Switch kinks to be worked out (ALL consoles suck in the first year!) then consider buying in.
